3 * [shogi-server] Write more game results in record files
4 As the CSA Record Format standard states, "%TIME_UP" and
5 "%SENNICHITE" are now recorded in CSA files when a game ends for
6 timed up or sennichite respectively.
8 * [shogi-server] [mk_game_results] Change schema to add number of
9 moves The format of an internal game result summary file, '00LIST',
10 has been changed to add number of moves of a game, which would be of
11 help for a script calculating rating scores.
13 * Update Revision to 20170902
15 2017-02-26 Daigo Moriwaki <daigo at debian dot org>
17 * utils/csa-filter.rb: Allow csa-filter.rb to filter games by a winner or loser
18 New command lines, --winner <player> or --loser <player>, are now
19 supported to supply extra filtering conditions. Note that each
20 filter is combined as AND condition.
22 - % ./csa-filter.rb ~/Downloads/20160314 --white gpsfish_xeon --loser gpsfish_xeon
23 - % ./csa-filter.rb ~/Downloads/20160314 --white gpsfish_xeon --winner gpsfish_xeon
26 2016-12-11 Daigo Moriwaki <daigo at debian dot org>
28 * Update Revision to 20161211.
31 2016-12-09 Daigo Moriwaki <daigo at debian dot org>
33 * Allow util/statistics.rb to set a filtering condition of found files
34 Regarding util/statistics.rb, add a new command line option,
35 --filter regexp, to process files that are matched with a regexp.
36 It would make it easier to calculate statistics of certain games.
39 2016-11-26 Daigo Moriwaki <daigo at debian dot org>
41 * [shogi-server] Allow to customize maximum lenght of a login indentifier
43 - The current maximum length of a login identifier is 32. Some
44 private uses require longer player names to distinguish each other
45 by specifying randomly generated tokens. It would of help to add a
46 new command line option --max-identifier to overwrite the default
48 * Build a Docker image for Shogi-server
50 - Build a Docker image
52 - Running a local shogi-server would look like
53 % docker pull shogiserver/shogiserver
54 % docker run -p 4081:4081 -v `pwd`/logs:/logs shogiserver/shogiserver
55 * [shogi-server] shogi_server/game.rb:
56 - Remove a debug message
58 2016-04-09 Daigo Moriwaki <daigo at debian dot org>
61 - Support Fischer time control.
62 * [shogi-server] Bump up the revision to 20160409.
64 2016-04-02 Daigo Moriwaki <daigo at debian dot org>
66 * [shogi-server] Support Fischer Time Control
68 - Fischer time control means that:
69 Before a player has made their move, a specified time increment is
70 added to their clock. Time can be accumulated, so if the player
71 moves within the delay period, their remaining time actually
73 (https://en.wikipedia.org/wiki/Chess_clock)
74 - New syntax of game names:
75 An 'F' suffix denotes a Fisher time in seconds. For example,
76 "floodgate-600-10F" specifies
78 + Total allotted time is 600 seconds for each player
79 + 10-second increment before a player's move in a Fischer way
80 - The server now proposes game conditions upon a game start with
81 - "Protocol_Version 1.2"
82 - "Increment:<n>" for Fischer Time Control
83 - Kifu files can include the following comment for Fischer Time
86 * [shogi-server] Fix some lint warnings.
88 2015-12-13 Daigo Moriwaki <daigo at debian dot org>
90 * [shogi-server] Enhance capability of Floodgate configuration file
91 - New parameter: Max_Moves, defined in the CSA protocol
93 - New parameter: Least_Time_Per_Move, defined in the CSA protocol
94 ex. set Least_Time_Per_Move 0
95 - Proposed messages distributed to each player upon starting a new
96 game will include Max_Moves as well as Least_Time_Per_Move.
97 - CSA files produced by the server will include settings of
98 Max_Moves and Least_Time_Per_Move in comment lines as follows:
100 'Least_Time_Per_Move:0
101 - The official Shogi-server on wdoor.c.u-tokyo.ac.jp will
102 be running with different parameters, depending on game names.
103 a) Max_Moves will be 256 for floodgate-600-10 games;
105 b) Least_Time_Per_Move will be 0 for floodgate-600-10 games;
108 * [shogi-server] shogi_server/pairing.rb:
109 - LeastDiff attempts more trials, depending of a number of players
110 to be matched, top achieve more optimized matching combinations.
112 2015-11-27 Daigo Moriwaki <daigo at debian dot org>
114 * [shogi-server] shogi_server/time_clock.rb:
115 - A time consumed could be -1.
116 * The start time of a move is captured after sending a move to a
117 player of the next turn at the end of the giant lock
118 * The end time of the move is captured at the exact time when the
119 server receives it before the giant lock
120 Therefore, end_time < start_time is possible when a player returns a
122 Thanks to Tomoyuki Kaneko for reporting this issue.
125 2015-02-14 Daigo Moriwaki <daigo at debian dot org>
127 * util/statistics.rb:
128 - Updated to investigate floodgate-600-10 games.
129 Consult the result at
130 http://www.sgtpepper.net/hyspro/diary/20150214.html.
131 - Added a companion R script: histogram.R
133 2015-02-01 Daigo Moriwaki <daigo at debian dot org>
136 - shogi_server/login.rb: When players are logged in, log their
137 player_id if they have it.
139 2015-01-20 Daigo Moriwaki <daigo at debian dot org>
142 - Getting an absolute path of this file was wrong if it was a
143 symbolic link. This issue has been addressed.
145 - Links to details pages for players now use a relative path so
146 that it works on a testing site.
148 2015-01-17 Daigo Moriwaki <daigo at debian dot org>
151 - shogi-server, shogi_server/{command,game_result,player}.rb:
152 The change at 2014-10-13 was not worked as expected. Reworked.
153 A player, attempting to login with the current live player
154 stalling for more than a day, can forcibly override the current
157 2015-01-12 Daigo Moriwaki <daigo at debian dot org>
160 - shogi_server.rb: Follow an API change in a upstream class:
161 LogDevice.previous_period_end
163 2014-12-27 Daigo Moriwaki <daigo at debian dot org>
166 - When a non-rated player participates in Floodgate, the following exception
167 was thrown and a Floodgate game would not start:
168 undefined method `[]' for nil:NilClass
169 ["/home/shogi-server/www/x/shogi_server/pairing.rb:499:in `block
170 in calculate_diff_with_penalty'"
171 This issue has been resolved. Only players who have player ID
172 (i.e. those who log in with valid password) are now allowed to
173 participate in Floodgate as the spec web page
174 [http://shogi-server.sourceforge.jp/rating.html] describes.
176 2014-12-23 Daigo Moriwaki <daigo at debian dot org>
179 - Addressed Ruby incompatibility on ShogiServer::Usi::alphabetToDan.
180 It (and usiToCsa.rb) did not work with Ruby 1.9.3. This issue
182 Thanks to Hiraoka-san for debugging.
184 2014-12-18 Daigo Moriwaki <daigo at debian dot org>
186 * utils/eval_graph.rb:
187 - Gnuplot 4.6.6 drew evaluation-value lines with a dashed style.
188 This issue has now been addressed so that solid lines are used.
190 2014-11-30 Daigo Moriwaki <daigo at debian dot org>
195 2014-11-24 Daigo Moriwaki <daigo at debian dot org>
198 - Ruby 2.0.0 or later is recommended to use with shogi-server
199 since Ruby 1.8 reached its End-of-Life on the end of July, 2014.
201 - Addressed a warning of duplicated range in a regular expression.
203 2014-10-13 Daigo Moriwaki <daigo at debian dot org>
206 - A player, attempting to login with the current live player
207 stalling for more than a day, can forcibly override the current
209 - Kifu record files now includes rating scores of players at the
210 time when games start. Previously, for rating games, a record
211 file includes player IDs of both players with a line starting with
212 "'rating". Now it also shows rating scores for players who have
213 valid scores. The formats for black and white players are as
215 'black_rate:<player_id>:<score>
216 'white_rate:<player_id>:<score>
218 'rating:Test_sente+275876e34cf609db118f3d84b799a790:Test_gote+275876e34cf609db118f3d84b799a790
219 'black_rate:Test_sente+275876e34cf609db118f3d84b799a790:2763.0
220 'white_rate:Test_gote+275876e34cf609db118f3d84b799a790:2345.0
222 2014-10-12 Daigo Moriwaki <daigo at debian dot org>
225 - New feature: max moves
226 - New command line option: --max-moves n
227 When a game with the n-th move played does not end, make the
228 game a draw (default 256 in compliance with CSA Protocol V1.2
229 or later). Setting 0 disables this feature for
230 CSA Protocol V1.1.2 or before.
231 - Players will receive a new message, "#MAX_MOVES", upon an end
235 - A new log summary type, "max_moves", has been assigned for games
236 drawing with max moves.
237 'summary:max_moves:name_sente draw:name_gote draw
238 - Least time per move:
239 - New command line option: --least-time-per-move n
240 This option specifies a least time in second per move, which
241 is 0 second by default, meaning that a decimal
242 fraction of time for a move will be truncated in compliance
243 with CSA Protocol V1.2 or later.
244 Set 1 for CSA Protocol V1.1.2 or before.
246 2014-07-19 Daigo Moriwaki <daigo at debian dot org>
249 - Added a new option, --abnormal-threshold n:
250 Games that end with the 'abnormal' status are counted in
251 win/lost games for the rating calculation if a game plays more
252 than n plies. Otherwise (or if n is zero), abnormal games are
253 counted out of rating games.
255 2014-01-07 Daigo Moriwaki <daigo at debian dot org>
258 - Released: Revision "20140107"
260 2013-12-29 Daigo Moriwaki <daigo at debian dot org>
263 - Previously, parameters in Floodgate time configuration file were
264 not applied to actual instances. This issue has been fixed.
266 2013-12-21 Daigo Moriwaki <daigo at debian dot org>
269 - shogi_server/pairing.rb: Impose penalty on matches between
272 2013-12-15 Daigo Moriwaki <daigo at debian dot org>
275 - Listen on only IPv4 explicitly. Under ruby 1.9.3p194, without
276 any bind addresses, ruby attempts to listen on both "0.0.0.0"
277 and "::". Specifying "::" on Linux leads to listen on both IPv4
278 and IPv6, which results in a warning message saying "Address
279 already in use - bind(2)".
281 - Released: Revision "20131215"
283 2013-12-14 Daigo Moriwaki <daigo at debian dot org>
286 - Added a new program, bin/usiToCsa.rb, which is a bridge for a
287 USI engine to connect to the Shogi-server.
288 - bin/usiToCsa is a sample wrapper script.
290 2013-12-13 Daigo Moriwaki <daigo at debian dot org>
293 - shogi_server/league/floodgate_thread.rb:
294 - Added a log message.
296 2013-12-08 Daigo Moriwaki <daigo at debian dot org>
299 - shogi-server/shogi_server/pairing.rb:
300 - Modified comment for LeastDiff match.
301 - Changed log messages and levels.
303 2013-12-07 Daigo Moriwaki <daigo at debian dot org>
306 - shogi_server/pairing.rb, player.rb:
307 Simplify estimated rate of unrated players (less memory).
308 - Enhanced syntax of Floodgate time configuration file.
309 Now it supports "set sacrifice <player_id>"; it sets a
310 sacrificed player for a specific Floodgate game.
311 ex. set sacrifice gps500+e293220e3f8a3e59f79f6b0efffaa931
313 2013-12-05 Daigo Moriwaki <daigo at debian dot org>
316 - Added a new pairing method, ShogiServer::ExcludeUnratedPlayers,
317 which filters out unrated players.
318 - Enhanced syntax of Floodgate time configuration file.
319 Now it supports "set pairing_factory <function_name>"; it sets a
320 factory function name generating a pairing method which will be
321 used in a specific Floodgate game.
322 ex. set pairing_factory floodgate_zyunisen
323 - Implemented conversion of move representation between CSA format
326 2013-11-24 Daigo Moriwaki <daigo at debian dot org>
329 - shogi_server/league/floodgate.rb: Improved robustness against
330 empty file under ruby 1.9.3p194
332 - Previously, reloading in daemon mode failed on
333 ruby 1.9.3p194. This issue has been fixed.
334 - Listen on only IPv4 explicitly. Under ruby 1.9.3p194, without
335 any bind addresses, ruby attempts to listen on both "0.0.0.0"
336 and "::". Specifying "::" on Linux leads to listen on both IPv4
337 and IPv6, which results in a warning message saying "Address
338 already in use - bind(2)".
340 - Fixed for reading Japanese comments under ruby1.9.3p194.
341 * mk_rate-from-grep, mk_rate-grep:
342 - Removed files that are no longer used.
344 2013-11-23 Daigo Moriwaki <daigo at debian dot org>
347 - gsl library may be provided as a gem
348 - Now duplicated inputs are checked and skipped.
349 * test/TC_floodgate.rb
350 - Improved randomness check so that it works on Ruby 2.0.0 as well
352 2013-11-04 Daigo Moriwaki <daigo at debian dot org>
355 - Added a new option, --ignore, which is imported from
358 - Flush after each output line.
359 * Rleased: Revision "20131104"
361 2013-09-08 Daigo Moriwaki <daigo at debian dot org>
364 - shogi_server/{game,time_clock}.rb:
365 When StopWatchClock is used, "Time_Unit:" of starting messages
366 in CSA protocol supplies "1min".
368 2013-04-07 Daigo Moriwaki <daigo at debian dot org>
371 - shogi_server/{game,time_clock}.rb:
372 Adds variations of thinking time calculation: ChessClock
373 (current) and StopWatchClock (new).
374 StopWatchClock, which is usually used at official games of human
375 professional players, is a clock where thiking time less than a
376 miniute is regarded as zero.
377 To select StopWatchClock, use a special game name with "060"
378 byoyomi time. ex. "gamename_1500_060".
380 2013-03-31 Daigo Moriwaki <daigo at debian dot org>
383 - %%FORK command: %%FORK <source_game> [<new_buoy_game>] [<nth-move>]
384 The new_buoy_game parameter is now optional. If it is not
385 supplied, Shogi-server generates a new buoy game name from
387 - command.rb: More elaborate error messages for the %%GAME command.
389 2013-03-20 Daigo Moriwaki <daigo at debian dot org>
392 - New pairing algorithm: ShogiServer::Pairing::LeastDiff
393 This pairing algorithm aims to minimize the total differences of
394 matching players' rates. It also includes penalyties when a match
395 is same as the previous one or a match is between human players.
396 It is based on a discussion with Yamashita-san on
397 http://www.sgtpepper.net/kaneko/diary/20120511.html.
399 2013-02-23 Daigo Moriwaki <daigo at debian dot org>
402 - New command: %%FORK <source_game> <new_buoy_game> [<nth-move>]
403 Fork a new game from the posistion where the n-th (starting from
404 one) move of a source game is played. The new game should be a
405 valid buoy game name. The default value of n is the position
406 where the previous position of the last one.
407 - The objective of this command: The shogi-server may be used as
408 the back end server of computer-human match where a human player
409 plays with a real board and someone, or a proxy, inputs moves to
410 the shogi-server. If the proxy happens to enter a wrong move,
411 with this command you can restart a new buoy game from the
412 previous stable position.
413 ex. %%FORK server-denou-14400-60+p1+p2+20130223185013 buoy_denou-14400-60
415 2012-12-30 Daigo Moriwaki <daigo at debian dot org>

466 This issue has been fixed.
468 2011-12-18 Daigo Moriwaki <daigo at debian dot org>
471 - shogi_server/board.rb, piece.rb: Refactoring to cache OU pieces,
472 which was inspired by 81SquareShogi-server's change
473 (74b24b88c843f1dd767412475b117481d1d5e8eb).
474 - Added shogi-server-profile to take profile of shogi-server.

501 - mk_rate: the usage was not updated.
502 Thanks to Hoki-san to report this issue. (Closes: #23358)
504 2010-09-18 Daigo Moriwaki <daigo at debian dot org>
507 - shogi_server/board.rb, game.rb: For hadicapped games, wrong
508 initial positions were delivered to players and monitors. This
509 issue has been fixed. (Closes: #23245)
510 Thanks to HIDETCHI for reporting the issue.
512 2010-09-05 Daigo Moriwaki <daigo at debian dot org>
515 - shogi_server/login.rb: Enhanced the CSA Login mode.
516 Logging in the server with the CSA mode, users are now allowed to
517 specify a turn preference in an enhanced gamename string which
518 looks like <gamename>-<time>-<time>-<turn>. The first three
519 parts are a regular game definition. The last "-<turn>"
521 + Without -<turn> (i.e. same as the previous behavior), there
522 is no turn preference. A user's turn will be defined randomly.
523 + <turn> is either "B" for black or "W" for white.
525 2010-09-04 Daigo Moriwaki <daigo at debian dot org>
528 - shogi_server/{board,command,game,league,player}.rb
529 The Buoy behavior is changed.
530 + Starting a buoy game, players are notified a starting game
531 position with the initial position and moves, instead of a
533 + Players are allowed to start buoy games with specific turns.
534 ex. %%GAME buoy_foo-1500-0 +
536 2010-08-05 Daigo Moriwaki <daigo at debian dot org>
539 - shogi_server/command.rb: Prevent a possible password from be
540 logged in a log file when players send invalid LOGIN-like commands.
541 Thanks to Tomoyuki Kaneko for this idea.
543 2010-08-03 Daigo Moriwaki <daigo at debian dot org>
546 - sample/{check_file.rb,check_time.rb,check_time2.rb,test_time.rb}:
547 Added new files to test an issue where mtime of log files was
548 earlier than system time.
549 - shogi_server/league/floodgate_thread.rb: SetupFloodgate#start
550 now returns an instance correctly.
551 - ../shogi_server.rb, ../shogi_server/util.rb: Refactored
552 mkdir_for to Mkdir.mkdir_for.
553 - ../shogi_server/game.rb: mkdir_p will be performed in a global
554 mutex of ShogiServer::Mkdir.
556 2010-07-25 Daigo Moriwaki <daigo at debian dot org>
559 - shogi_server/command.rb:
560 + For an unknown error command log, an empty line is no longer logged.
561 + Commands specific to 81Dojo, starting with '%%%', are just
562 ignored instead of unknown command errors.
564 + Refactoring. Added test/TC_logger.rb to test
565 ShogiServer::Logger class.
566 + Fixed race condition: creating a new directory to archive
567 logs may have caused race condition, which ended up with
568 making the server unavailable. This issue has been fixed.
570 + Improved fault tolerance of the server.
572 2010-07-23 Daigo Moriwaki <daigo at debian dot org>
575 - shogi_server/league/floodgate_thread.rb: When the server run
576 with DEBUG mode, it ended up with an undefined variable error.
577 This issue has been fixed.
579 2010-07-17 Daigo Moriwaki <daigo at debian dot org>
582 - shogi_server.rb, shogi_server/board.rb, shogi_server/move.rb
583 - Refactoring: Board can now move_to() and move_back() a move
584 instead of deep_copy().
586 2010-07-11 Daigo Moriwaki <daigo at debian dot org>
589 - shogi_server/player.rb: Set initial values to BasicPlayer's
591 - shogi_server/league.rb: Improved performance of
592 Persistant#get_players. It took about 20 seconds for a large
593 size of players (5,300 lines in players.yaml). Now it completes in an
596 2010-06-22 Daigo Moriwaki <daigo at debian dot org>
599 - A new command line option:
600 --floodgate-names GameStringA[,GameStringB[,...]]
601 where a game string should be a valid game name such as
604 Note: Without this option, no floodgate games are started. If
605 you want floodgate-900-0 to run, which was default enabled in
606 previous versions, you need to specify the game name in this new
608 - Floodgate time configuration file:
609 You need to set starting times of floodgate groups in
610 configuration files under the top directory. Each floodgate
611 group requires a corresponding configuration file named
612 "<game_name>.conf". The file will be re-read once just after a
615 For example, a floodgate-3600-30 game group requires
616 floodgate-3600-30.conf. However, for floodgate-900-0 and
617 floodgate-3600-0, which were default enabled in previous
618 versions, configuration files are optional if you are happy with
619 default time settings.

639 - shogi_server/command.rb: Fixed an issue that MONITOR2OFF did not
640 work. Thanks to HIDECHI and koudayu.
642 2010-05-10 Daigo Moriwaki <daigo at debian dot org>
645 - test/*.rb: Improved performance and stability of tests
646 - shogi_server/player.rb: Help the write_thread to terminate
648 2010-05-06 Daigo Moriwaki <daigo at debian dot org>
651 - Previously mk_rate did not count in draw games. Now a draw game
652 is considered to weight 0.5 win and 0.5 loss. Respect
653 Inaniwa-shogi which strategically aims to draw.
654 - a new command line option, --skip-draw-games. In this mode, draw
655 games are just ignored as mk_rate previously did.
657 2010-04-25 Daigo Moriwaki <daigo at debian dot org>
660 - shogi_server/player.rb:
661 Log a warning message in a case that a player closes a
664 2010-04-13 Daigo Moriwaki <daigo at debian dot org>
667 - shogi_server/command.rb:
668 Equality of MonitorHandler class was wrong. %%MONITOROFF and
669 %%MONITOR2OFF may cause unexpected behavior. This issue has been
670 fixed. Thanks to Kota Fujiwara for reporting.
672 2010-03-07 Daigo Moriwaki <daigo at debian dot org>
675 - If two sequential moves from a player are identical, the last
676 one will be ignored and a game is in play. This situation might
677 happen with human players, especially on slow network,
678 impatiently sending a move twice.
680 2010-02-27 Daigo Moriwaki <daigo at debian dot org>
683 - The server now provides more accurate time control. Previously,
684 a player's thinking time included a time waiting to get the giant
685 lock. This may have caused games to time up, especially, during
688 2010-01-22 Daigo Moriwaki <daigo at debian dot org>
691 - Experimental feature: support handicapped games.
692 Game names that have the following prefixes are recognized as
693 handicapped games. Turn symbols "+" and "-" mean Uwate (expert)
694 and Shitate (beginner) respectively (i.e. Uwate players first).
695 "*" is not available.
705 2010-01-16 Daigo Moriwaki <daigo at debian dot org>
708 - shogi_server/command.rb, test/TC_command.rb
709 Proposal implementation of a new command called MONITOR2{ON,OFF}.
710 When the MONITOR2ON command is issued by a player, the server
711 immediately sends the player the entire contents of a record
712 file of the game, i.e. history of moves and so on, at that time.
713 Then, the server will forward subsequent moves like they are
714 appended to the record file.
715 - Behavior changed: A player monitoring a game with MONITORON will
716 not receive Game#show again when a gaming player resigns (:toryo).
718 2010-01-10 Daigo Moriwaki <daigo at debian dot org>
720 * Converted the repository from Subversion to Git.
722 2009-12-26 Daigo Moriwaki <daigo at debian dot org>
725 - The server can now provide multiple floodgate modes such as
726 floodgate-900-0 and floodgate-3600-0.
728 2009-12-25 Daigo Moriwaki <daigo at debian dot org>
731 - shogi-server: The command line option --floodgate-history has
732 been deprecated. The server will decide history file names such
733 as 'floodgate_history_900_0.yaml' and
734 'floodgate_history_3600_0.yaml', and then put them in the top
737 2009-12-20 Daigo Moriwaki <daigo at debian dot org>
740 - shogi_server/player.rb: Added new methods: is_human? and
742 A human player is recommended to use a name ending with '_human'.
743 ex. 'hoge_human', 'hoge_human@p1'
744 - shogi_server/pairing.rb: Added a new class:
745 StartGameWithoutHumans, which tries to make pairs trying to
746 avoid a human-human match. This is now enabled instead of the
747 previous class: StartGame.
748 - shogi-server, shogi_server/league/floodgate.rb:
749 Changed the argument of Floodgate.new.
751 2009-12-04 Daigo Moriwaki <daigo at debian dot org>
754 - The HUP signal is not supported by Ruby on Windows.
756 2009-11-11 Daigo Moriwaki <daigo at debian dot org>
759 - Added a new command line option: --base-date. You can specify a
760 base date to calculate rating scores. Games in the `future' are
761 ignored for the calculation.
763 2009-11-10 Daigo Moriwaki <daigo at debian dot org>
766 - The server logs a result of each game to a file named '00LIST',
767 which will be used to generate players.yaml. If the file does
768 not exist, the server will create one automatically.
769 Instruction to use the game result list file:
770 1. Make a list of game results from existing CSA files with
772 % ./mk_game_results dir_of_csa_files > 00LIST
773 2. Run the server. It appends a result of each game to
774 '00LIST' when the game finishes.
775 3. From the list of game results, calculate rating scores of
777 % ./mk_rate 00LIST > players.yaml
779 2009-11-08 Daigo Moriwaki <daigo at debian dot org>
782 - Split a pre-process collecting game results from csa files into
783 a new command, mk_game_results. Now, Generating players.yaml
784 requires two steps as follows:
785 % ./mk_game_results dir_of_csa_files > 00LIST
786 % ./mk_rate 00LIST > players.yaml
788 % ./mk_game_results dir_of_csa_files | ./mk_rate > players.yaml
791 2009-08-06 Daigo Moriwaki <daigo at debian dot org>
794 - A experimental new feature, codenamed Buoy: it allows players to
795 play a game starting with a specified position. First, a player
796 sets a buoy game with moves to a specific position. Then, two
797 players can play a new game with the game name.
799 + %%SETBUOY <game_name> <moves> [count]
801 ex. %%SETBUOY buoy_foo-900-0 +7776FU 10
802 ex. %%SETBUOY buoy_foo-1500-0 +7776FU-3334FU
803 - game_name is a valid game name with a prefix "buoy_".
805 - moves are initial moves from the Hirate position to a
806 specific position that you want to start with.
807 ex. +7776FU-3334FU+8786FU
808 - count is an optional attribute to tell how many times the
809 game can be played (default 1). The count is decremented
810 when the game finishes. If the count reaches zero, the buoy
811 game is removed automatically by the server.
813 + %%DELETEBUOY <game_name>
814 Delete a buoy game. The only owner who set up the game is
815 allowed to delete it.
816 ex. %%DELETEBUOY buoy_foo-900-0
817 - game_name is the buoy game name that was created.
818 + %%GETBUOYCOUNT <game_name>
819 Show a current count of the buoy game or -1 for non-existing
823 2009-07-11 Daigo Moriwaki <daigo at debian dot org>
826 - shogi_server/command.rb: refactored commands out of player.rb.
828 2009-06-18 Daigo Moriwaki <daigo at debian dot org>
831 - An empty floodgate_history.yaml caused a server error. This
832 issue has been fixed.
835 2009-06-17 Daigo Moriwaki <daigo at debian dot org>
838 - If a new game matched between two players is not started within
839 a certain time (default 120 seconds) (i.e. the agree_waiting or
840 start_waiting state lasts too long), the Server REJECTs the game.
843 2009-06-15 Daigo Moriwaki <daigo at debian dot org>
846 - When a Gote player AGREEd a new game and then a Sente player
847 logged out (LOGOUT), the Gote incorrectly received a LOGOUT message
848 from the server. Since Gote's state was not AGREEd or STARTed yet,
849 the Gote should be REJECTed. This issue has been fixed.
852 2009-06-14 Daigo Moriwaki <daigo at debian dot org>
855 - The Board could not recognize a certain pattern of
856 Oute-Sennichite. This issue has been fixed.
859 2009-03-22 Daigo Moriwaki <daigo at debian dot org>
861 * [utils/correct-bug14635.rb]
862 - Added a new file. This program corrects illegal lines introduced
865 2009-03-07 Daigo Moriwaki <daigo at debian dot org>
868 - Improved performance.
870 2009-02-15 Daigo Moriwaki <daigo at debian dot org>
873 - A duplicated comment that is the one of the previous (or older)
874 move might be erroneously recorded in a csa file. This issue has
875 been fixed. (Closes: #15080)
877 2009-02-11 Daigo Moriwaki <daigo at debian dot org>
879 * [utils/csa-filter.rb]
880 - Added a new file. This program filters CSA files.
882 2009-02-01 Daigo Moriwaki <daigo at debian dot org>
885 - The shogi-server records csa files of games in an illegal
886 format. This issue has been fixed. (Closes: #14635)
887 - A ##[MONITOR] command for showing a game result such as %TORYO
888 was not correct. This issue has been fixed.
890 2009-01-13 Daigo Moriwaki <daigo at debian dot org>
893 - It failed to proccess a game result, OuteKaihiMoreWin where a
894 checked king does not escape. This issue has been fixed.
896 2009-01-02 Daigo Moriwaki <daigo at debian dot org>
899 - shogi_server/timeout_queue.rb: the timeout parameter of the
900 constructor was not respected erroneously. This issue
902 - shogi_server/players.rb: When a player was finishing with its
903 write socket broken, there was a chance that the thread of the
904 player in the giant lock had to wait for a long time (about 20
905 seconds), which might cause threads of other players stop and
906 time out. (Closes: #14469)
908 2008-12-30 Daigo Moriwaki <daigo at debian dot org>
911 - Added a new option: --footer filename, which inserts contents of
912 the filename at the bottom of a generated page. A text specific to
913 wdoor should be written by using this option.
915 - It does no more depend on RDoc. RDoc::usage does not work well
918 2008-12-28 Daigo Moriwaki <daigo at debian dot org>
921 - Check kifu files more carefully so that files that contain
922 incomplete records are skipped.
923 - mk_rate might have failed to alloc due to out of memory. Now it
924 consumes less memory (about 200MB instead of 2GB).
925 - File names can be put into STDIN instead of specifying directory
926 names in command line arguments.
928 - New file. It filters kifu files and is of use for a pre-filter
931 2008-12-13 Daigo Moriwaki <daigo at debian dot org>
934 - Improved an existance check and etc. of directories specified
935 by command line options, especially in case of the daemon mode.
937 - A rotated log file is moved to $topdir/YYYY/MM/DD.
940 2008-11-27 Daigo Moriwaki <daigo at debian dot org>
943 - Added sample/*.sh for command line samples.
945 2008-11-24 Daigo Moriwaki <daigo at debian dot org>
948 - Added a new option --floodgate-history, which allows users to
949 specify a file name that stores the records of games. The
950 records are taken care of when games are matched.
952 2008-10-18 Daigo Moriwaki <daigo at debian dot org>
954 * [utils/eval_graph.rb]
955 - Display time control graphs as well.
956 Thanks to Nishimura-san for this idea.
959 2008-10-08 Daigo Moriwaki <daigo at debian dot org>
962 - Ruby 1.8.7 (or later) must be used. Ruby 1.8.6 is not supported.
963 - Daemon mode is available.
964 - shogi_server/piece_ky.rb is again merged with
965 shogi_server/piece.rb, then has been removed.
966 - Added a test case, TC_usi.rb.
968 2008-06-30 Daigo Moriwaki <daigo at debian dot org>
971 - Added a new option --player-log-dir, which allows users to log
972 messages that are received or sent to the wire.
974 2008-06-28 Daigo Moriwaki <daigo at debian dot org>
977 - A rating comment line is now written before the first move in a
978 record file instead of after the last move, which allows other
979 applications watching a game to recognize players in the middle
980 of the game. (Closes #12821)
981 - If a player, including a monitor, stuck at the time of sending
982 messages to the wire, which means that the giant lock was locked,
983 it might have prevented other players from processing until
984 timeout occurred. This issue has been fixed. (Closes #12555)
986 2008-06-27 Daigo Moriwaki <daigo at debian dot org>
989 - Pairing players might not have shuffled players because of
990 poor shuffling algorithm. This issue has been fixed.
993 2008-06-25 Daigo Moriwaki <daigo at debian dot org>
996 - Check invalid arguments. (Closes: #12856)
998 2008-06-23 Daigo Moriwaki <daigo at debian dot org>
1001 - Added a new option: --fixed-rate and --fixed-rate-player
1002 whose rate always results in that rate. (Closes: #12800)
1004 2008-06-06 Daigo Moriwaki <daigo at debian dot org>
1007 - The source has been splited to multiple sub files.
1008 - The program now depends on rubygems and activesupport.
1009 - The program can reload the source files on the flight, by
1010 sending a HUP signal to the server.
1011 - The server log will be rotated daily.
1013 2008-05-18 Daigo Moriwaki <daigo at debian dot org>
1016 - Last game results (win or lose) of x1 players were not
1017 available on the next game. This issue has been fixed.
1018 Thanks to Tomoyuki Kaneko for debugging.
1019 - For draw games, "'rating" line in a .csa file was
1020 wrong (meaningless). This issue has been fixed.
1022 2008-05-16 Daigo Moriwaki <daigo at debian dot org>
1025 - The repository has been converted from CVS to Subversion.
1027 2008-05-13 Daigo Moriwaki <daigo at debian dot org>
1030 - Floodgate's thread could cause an error when players.yaml was
1031 cleared by another program (mk_rate). This issue has been
1033 - Give default values to BasicPlayer, which fixed undefined
1034 method error in Pairing.
1036 2008-05-10 Daigo Moriwaki <daigo at debian dot org>
1039 - The server could not recognize uchifuzume as an illegal move.
1040 This bug has been fixed.
1041 - The server crashed by an undefined method error.
1042 This issue has been fixed.
1044 2008-05-05 Daigo Moriwaki <daigo at debian dot org>
1047 - .csa files will be located in a sub directory such as
1048 "2008/05/05/*.csa". These days, we have many games in a day.
1049 This change will help users browse a file list.
1051 2008-05-03 Daigo Moriwaki <daigo at debian dot org>
1054 - Show players who have accessed in the last 30 minutes with
1057 2008-04-22 Daigo Moriwaki <daigo at debian dot org>
1060 - When YSS was not rated on the wdoor mode, wrong rate24 scores
1061 were displayed. This issue has been fixed. Now YSS absence
1064 2008-04-21 Daigo Moriwaki <daigo at debian dot org>
1067 - The half-life period is now configurable.
1068 ex $ ./mk_rate --half-life 14 --half-life-ignore 7 <records>
1070 2008-04-12 Daigo Moriwaki <daigo at debian dot org>
1073 - Renamed variables (@id) since they caused Ruby's warning.
1075 2008-04-11 Daigo Moriwaki <daigo at debian dot org>
1078 - Improved a way to handle diferred moves (2008-03-24's change),
1079 based on Tomoyuki Kaneko's patch.
1081 2008-04-01 Daigo Moriwaki <daigo at debian dot org>
1084 - An incorrect LOGIN crashed the server. This issue has been
1087 2008-03-24 Daigo Moriwaki <daigo at debian dot org>
1090 - Converting characters for comments in moves caused an error. This
1091 issue has been fixed.
1092 - If a player moves in the opponent's turn, it is illegal. But the
1093 current CSA protocol does not clearly define a way to tell so to
1094 the players. This shogi-server internally keeps such a move in a
1095 buffer and replay it when the player of the move gets his/her
1098 2008-03-16 Daigo Moriwaki <daigo at debian dot org>
1101 - Erroneously, Board#to_s's current player was always Black.
1102 It caused wrong determination of sennichite since it did not
1103 care about the current player of a state. This has been fixed.
1104 Thanks Takada-san for reporting this bug.
1106 2008-03-10 Daigo Moriwaki <daigo at debian dot org>
1108 * [util/players-graph.rb]
1109 - Applied Kaneko-san's patch, which also shows expected-rate24
1111 - Small PNG gets smaller.
1113 2008-03-08 Daigo Moriwaki <daigo at debian dot org>
1116 - Added an option --wdoor. In this mode, a rate expected at Shogi
1117 Club 24 is calculated from YSS's rating (he is 2400 now).
1119 2008-03-04 Daigo Moriwaki <daigo at debian dot org>
1122 - If the computed ratings do not stabilize, then mk_rate aborts.
1123 $ ./mk_rate dir && ./mk_rate dir > players.yaml
1124 can avoid rewriting the invalid ratings to the file.
1126 2008-02-23 Daigo Moriwaki <daigo at debian dot org>
1129 - A comment is converted to EUC-JP and then written in a log.
1130 Note that this conversion guesses the input encoding. Clients
1131 are recommended to send EUC-JP compatible strings to the
1134 2008-02-21 Daigo Moriwaki <daigo at debian dot org>
1136 * [util/players-graph.rb]
1137 - Released. Draw a chart for a player's rating score.
1139 2008-02-17 Daigo Moriwaki <daigo at debian dot org>
1142 - An illegal teban specified for Floodgate login could crash the
1143 server. This issue has been fixed.
1145 2008-02-16 Daigo Moriwaki <daigo at debian dot org>
1148 - Thread.abort_on_exception is now false, meaning that
1149 a thread's abort does not affect the others.
1150 - The uchifuzume check did not generate promoting moves, which
1151 could crash the server with illegal moves. This issue has
1154 2008-02-14 Daigo Moriwaki <daigo at debian dot org>
1157 - Added a new pairing variation, Swiss-like style. Winners at the
1158 previous games (his/her point of view, not the server's) are
1159 paired first, and then the others are matched. This is the
1161 - Pairing classes are located in a separate source file,
1162 pairing.rb. The file is 'load'ed each time to be used,
1163 meaning that modifying the code will be applied to a running
1165 - You can specify a single player who will be out of pairing
1166 when there are odd players waiting for Floodgate.
1168 2008-02-13 Daigo Moriwaki <daigo at debian dot org>
1171 - When there are odd players wating for Floodgate, the random
1172 pairing deletes the player who has ever played the most games.
1174 2008-02-08 Daigo Moriwaki <daigo at debian dot org>
1177 - For the Not-Yet-Rated group, those who have not connected
1178 recently are not listed.
1180 - Floodgate's thread checks the current time each 10 secs.
1182 2008-02-05 Daigo Moriwaki <daigo at debian dot org>
1184 * [mk_rate] [mk_html]
1185 - Display not-yet-rated players as well.
1187 - Use Yahoo! UI Library.
1189 2008-02-04 Daigo Moriwaki <daigo at debian dot org>
1191 * [shogi-server] [webserver]
1192 - In the daemon mode, if the specified directory was a relative
1193 path, the server could fail to start with a permission denied
1194 error. This issue has been fixed. The path is interpreted as
1195 an absolute path before switching to daemon.
1196 - In the daemon mode, a wrong process id was written in
1197 '--pid-file'. This issue has been fixed. Also, the pid file
1198 will be removed when the server shuts down.
1200 2008-02-03 Daigo Moriwaki <daigo at debian dot org>
1203 - Game names that are recognized as the floodgate mode are now
1204 /^floodgate-\d+-\d+$/.
1205 - Floodgate could not schedule the next time when it was the next
1206 day. This issue has been fixed.
1208 2008-02-02 Daigo Moriwaki <daigo at debian dot org>
1211 - Implemented a new feature, Floodgate mode, for covenience with
1212 public rating games. Now there is a special game "wdoor-900-0".
1213 Matching players for that game is scheduled each 30 minitues.
1215 2007-11-03 Daigo Moriwaki <daigo at debian dot org>
1218 - Support Ruby 1.8.6 patch level 111 (or higher) and GSL 1.10 (or higher).

1224 - The logic to detect Oute-Sennichite was not complete. Both players
1225 (checking side and escaping side) may cause Oute-Sennichite. The old

1228 2007-06-16 Daigo Moriwaki <daigo at debian dot org>
1231 - Initial version. This web server is an interface between HTTP and

1233 of now %%LIST and %%WHO commands are supported.

1241 - Implemented `CHALLENGE' command, and the server will respond with
1242 `CHALLENGE ACCEPTED'. Note that this command is dummy for this server
1243 because it is only available for CSA's official testing server and does
1244 not belong to the CSA standard protocol. Therefor, when clients receive
1245 `CHALLENGE ACCEPTED' from this server, they must ignore it.
1246 - Show revision in a start up message.
1248 2007-04-01 Daigo Moriwaki <daigo at debian dot org>
1251 - Implemented one of the keepalive protocol in CSA protocol; If clients
1252 send LF, the server sends back LF.

1294 network failure or communication error. Recently some programs seem
1295 to have a lot of tries to connect to the Shogi Server at wdoor for
